The former is not convenient for quick disassembly and assembly due to its irregular shape and multiple sets of bolts, and has high requirements for installation accuracy; the latter's actual maximum operating speed is 3000rpm, which still needs to be improved, and the latter is very noisy at high speed (greater than the national standard requirement of 85 decibels for the operation of granulator equipment), which greatly shortens its service life.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0021] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0022] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1~Figure 3 As shown, it shows a high-speed wet granulator in one embodiment of the present disclosure, which includes a pot body 2 on a frame body 1, the frame body 1 has a main shaft portion 101, and a stirring shaft 3 coaxial with the main shaft portion 101 is rotatably arranged on the pot body 2; two ends of a flexible connecting wheel 4 are respectively sleeved on the stirring shaft 3 and the main shaft portion 101, and the stirring shaft 3 and the main shaft portion 101 are respectively meshed with two ends of the flexible connecting wheel 4.

[0025] As the current research institutions have put forward more requirements for the wet granulator in the laboratory, the coupling 11 currently used in the granulator, which has a crucial influence on the rotation speed, cannot meet the requirements of ultra-high speed, which is one of the most important requirements. For example, the geared nylon coupling 11 cannot exceed the maximum speed of 3000rpm, and due to its own structural material properties, it produces a lot of noise at high speed (greater than 85 decibels - the national standard for the operation of granulator equipment), and its service life will be greatly reduced.

[0026] The present disclosure improves the coupling 11, and uses a flexible connecting wheel 4 to be sleeved on the stirring shaft 3 and the main shaft part 101, and meshes with the two to complete the stable power transmission between the main shaft part 101 driven by the motor and the stirring shaft 3 in the pot body 2. For example, the two ends of the flexible connecting wheel 4 are respectively sleeved on the outer walls of the stirring shaft 3 and the main shaft part 101; for another example, the two ends of the flexible connecting wheel 4 are respectively sleeved on the inner walls of the stirring shaft 3 and the main shaft part 101. Regardless of the above form, it is necessary to ensure that the meshing shape of the connection part is adapted, such as the meshing of gear teeth, and the gear teeth on the flexible connecting wheel 4 are meshed. The tooth shapes are different, such as triangle, rectangle, etc., to achieve stable power transmission; specifically, the stirring shaft 3 and the end of the main shaft 101 can be installed with gears by bolts to complete the engagement with the teeth of the flexible connecting wheel 4, and further, a partial gap is left between the end of the stirring shaft 3 and the end of the main shaft 101 to accommodate the inner protrusion of the frame 1 to avoid interference between the two and ensure stable operation; through the above-mentioned structural improvement, the speed limitation of the existing coupling 11 is eliminated, and the maximum speed is increased to 5000rpm to adapt to more occasions and improve product quality.

[0027] Among them, the material used for the flexible connecting wheel 4 is soft material, such as rubber, silicone or nylon rubber, which greatly reduces the noise under high-speed operation, maintains it below 75 decibels, and prolongs the service life; further consideration is that the soft material connecting wheel is selected, and the number of teeth thereon will be limited, because if the number of teeth increases, on the one hand, it will greatly increase the difficulty of processing, and on the other hand, the tooth width will decrease, resulting in a decrease in the strength of the flexible connecting wheel 4, and the high-speed operation stability cannot be guaranteed. Therefore, specifically, determining the module to be 2-2.5 can determine a reasonable number of teeth, the pitch circle diameter d, the module m and the number of teeth z, z=d / m, and knowing the gear pitch circle diameter and module, the number of teeth can be calculated.

[0028] In addition, the customized coupling 11 structure not only meets the requirements of ultra-high speed and noise, but also improves the detachable operability, so that after the worker stops the machine, by adjusting the position of the stirring shaft 3 on the side of the pot body 2, or adjusting the position of the coaxial main shaft part 101, the flexible connecting wheel 4 sandwiched between the two can be pulled out to complete the disassembly. There is no need to remove the corresponding bolt group due to the irregular shape of its internal components like the traditional plum blossom coupling 11, which is not convenient for quick disassembly and assembly, and the traditional coupling 11 has high requirements for installation accuracy of ±0.05mm; similar elastic pin couplings 11, elastic sleeve pin couplings 11 and plum blossom couplings 11 are the same. Although the structure is similar to the present disclosure, they all have the above-mentioned disadvantages.

[0029] In addition, the base adopts a desktop installation design made of angle steel and sheet metal parts welded together, so that the equipment can be placed on the tabletop of a bedside office desk. This is because the current requirements for the size of equipment are becoming more and more compact, especially small wet granulators, which are indispensable process equipment in the pharmaceutical research and development and production stages.

[0030] During specific use, the pot body 2 is assembled on the table top of the frame body 1, and the stirring shaft 3 of the pot body 2 and the main shaft part 101 output by the main motor in the frame body 1 are connected through the flexible connecting wheel 4 to drive the stirring shaft 3 to rotate in the pot body 2, so that the stirring shaft 3 stirs and mixes the drug powder and the adhesive in the pot body 2 to complete the wet granulation operation process.

[0031] like Figure 3 , Figure 5 , Figure 6 , Figure 8 As shown, in some examples, the flexible connecting wheel 4 is a belt pulley, and two ends of the flexible connecting wheel 4 are respectively sleeved on the outer wall of the stirring shaft 3 and the outer wall of the main shaft part 101.

[0032] A flexible connecting wheel 4 in the form of a rubber pulley is selected, and its two ends are respectively sleeved on the outer wall of the stirring shaft 3 and the gears installed on the outer wall of the main shaft part 101, which mesh with each other, reduce noise, facilitate installation, and extend the service life of parts.

[0033] like Figure 3~Figure 8 As shown, in some examples, it also includes: the gear part 5 is movably arranged relative to the stirring shaft 3, one end of the flexible connecting wheel 4 is sleeved on the stirring shaft 3 through the gear part 5, and after the gear part 5 is subjected to external force, it moves and disconnects from the flexible connecting wheel 4.

[0034] During maintenance, the position of the main shaft portion 101 driven by the motor in the frame body 1 is generally not adjustable, and adjusting the position of the stirring shaft 3 similarly requires changing the position of the pot body 2. The position of the pot body 2 needs to be adjusted only for maintenance operations, which complicates the process. Generally, the pot body 2 is adjusted when the pot body 2 is replaced. Therefore, in order to further facilitate disassembly and maintenance, the flexible connecting wheel 4 sandwiched between the gear of the stirring shaft 3 and the gear of the main shaft portion 101 is pulled out.

[0035] The gear member 5 arranged on the stirring shaft 3 can be arranged to be movable relative to the axial direction thereof. An axial keyway can be arranged on the stirring shaft 3 in the form of a key connection. The gear member 5 cooperates with the keyway through a spline, which can adapt to the scenario of a wet granulator with a high torque. Therefore, the gear member 5 is sleeved on the stirring shaft 3 instead of being fixed on the stirring shaft 3 by bolts.

[0036] In certain emergency situations, such as when the equipment is operating abnormally, the operator discovers potential danger or other emergencies require disassembly, the worker only needs to use external force to push the gear part 5 on the stirring shaft 3 away from the main shaft part 101 to disconnect the connection between the gear part 5 and the flexible connecting wheel 4, achieve emergency braking, and perform maintenance, otherwise it can be installed.

[0037] At the same time, the above-mentioned form can flexibly control the connection and disconnection of the stirring shaft 3 and the power system according to different granulation process requirements. For example, the stirring shaft 3 may not need to rotate at certain stages of the granulation process. At this time, the connection is disconnected by the gear member 5, which can better control the progress of the granulation process and improve the controllability of the granulation process and the flexibility of the process.

[0038] like Figure 3 , Figure 4~Figure 7 As shown, in some examples, the outer wall of the stirring shaft 3 has a guide groove 301 with a length parallel to the axial direction of the stirring shaft 3, the gear part 5 is annular and is sleeved on the stirring shaft 3, and also includes a sliding guide part 6 arranged on the gear part 5 and one end of which is located in the guide groove 301.

[0039] It also includes an elastic member 7 sleeved on the stirring shaft 3, with two ends of the elastic member 7 respectively connected to the stirring shaft 3 and the gear member 5, for providing the gear member 5 with the force required for resetting after movement.

[0040] Finally, a guide groove 301-key groove is opened on the outer wall of the stirring shaft 3, and its length is set along the axial direction of the stirring shaft 3. A radial hole is opened in the annular gear part 5, and a sliding guide part 6 is threadedly arranged so that one end of it is exposed in the inner circle of the gear part 5 to ensure that one end can be located in the guide groove 301. The sliding guide part 6 is cylindrical and its diameter is equal to the width of the guide groove 301 to ensure that the gear part 5 can stably move along the axial direction of the stirring shaft 3 after being subjected to external force.

[0041] Further consideration is given to the low maintenance frequency and the short disassembly process, and there is no need to use additional external force to reset the gear part 5. Therefore, an elastic part 7 (spring) that automatically provides reset capability is added. The two ends of the elastic part 7 are respectively connected to the stirring shaft 3 and the gear part 5. A step ring portion is provided on the outer wall of the stirring shaft 3. The elastic part 7 is sleeved on the stirring shaft 3, with one end resting on the step ring portion and the other end resting on the side of the gear part 5. When the gear part 5 is moved away from the main shaft portion 101 by an external force and the disassembly and replacement are completed, the external force is directly canceled, and the gear part 5 is driven to move and reset under the action of the elastic part 7, and mesh with the flexible connecting wheel 4 again.

[0042] like Figure 3 , Figure 4 , Figure 7 , Figure 8As shown, in some examples, the gear part 5 has a force-bearing portion 501 at one end away from the flexible connecting wheel 4, and also includes a disassembly sleeve 8 movably arranged on the pot body 2, and its moving direction is axially colinear with the stirring shaft 3. The force-bearing portion 501 is located in the disassembly sleeve 8, and one end of the disassembly sleeve 8 has a disassembly step portion 801, which is used to drive the disassembly step portion 801 to push the force-bearing portion 501 after it moves.

[0043] Furthermore, it also includes a protective cover 9 arranged on the frame 1, and the main shaft portion 101 and the flexible connecting wheel 4 are both located in the protective cover 9. After the disassembly cover 8 is moved, it abuts or cancels the abutment with the protective cover 9, and after abutting the protective cover 9, the two are used to fully wrap the stirring shaft 3, the gear part 5, the flexible connecting wheel 4 and the main shaft portion 101.

[0044] The protection cover 9 and the disassembly cover 8 are added to provide comprehensive protection, reduce the contact between high-speed running parts and the outside world, reduce safety risks, and at the same time provide a more stable operating environment inside the equipment, reducing the impact of external factors such as dust and moisture on the equipment.

[0045] Therefore, a cylindrical disassembly sleeve 8 and a cylindrical protective sleeve 9 are installed around the stirring shaft 3 and the main shaft part 101. There are cylindrical parts extending from the pot body 2 around the stirring shaft 3. The disassembly sleeve 8 is slidably sleeved on the cylindrical part and slides along the axial direction of the stirring shaft 3. The protective sleeve 9 is similarly fixed to the frame 1 around the main shaft part 101 to protect the main shaft part 101 and the flexible connecting wheel 4 therein. Normally, part of the teeth of the gear part 5 on the stirring shaft 3 protrude from the disassembly sleeve 8, and a meshing space is reserved to facilitate stable connection with the flexible connecting wheel 4 in the protective sleeve 9 under the drive of the disassembly sleeve 8; before applying an external force to the disassembly sleeve 8 to drive the gear part 5 to move, one end of the disassembly sleeve 8 is aligned with one end of the protective sleeve 9, and the two are locked with a clamp to wrap the overall coupling 11-maintenance part therein to avoid misoperation.

[0046] Among them, in order to facilitate the disassembly sleeve 8 to drive the gear part 5 to move and avoid affecting the teeth and other parts thereon, the gear part 5 has a force-bearing part 501 at the end away from the flexible connecting wheel 4, that is, the end away from the teeth, and then a disassembly step part 801 is set at the position of the inner wall of the disassembly sleeve 8 corresponding to the force-bearing part 501, so as to complete the above-mentioned action; for example, a plurality of circumferentially arranged protrusions are integrally formed along the side wall of the cylindrical gear part 5, and a plurality of protrusions are integrally formed at the position of the inner wall of the disassembly sleeve 8 corresponding to the force-bearing part 501; for another example, an annular protrusion is integrally formed at the end of the gear part 5, and an annular disassembly step part 801 is integrally formed at the position of the inner wall of the disassembly sleeve 8 corresponding to the force-bearing part 501, and the inner diameter of the annular disassembly step part 801 is smaller than the inner diameter of the annular protrusion, which is convenient for applying external force and prevents the gear part 5 from detaching from the opening of the disassembly sleeve 8 after disassembly.

[0047] like Fig. 9As shown, in some examples, the pot body 2 is detachably set on the work surface 102 of the frame body 1, the stirring shaft 3 is rotatably set on the side wall of the pot body 2, and also includes a main slurry shaft 10 rotatably set at the bottom of the pot body 2, and its axial direction is perpendicular to the axial direction of the stirring shaft 3; the coupling 11 is set on the work surface 102 and is detachably connected to the coupling 11.

[0048] At present, the direction of replaceable pot body 2 also has broad prospects. It can meet various process requirements of different dosage requirements or mixed granulation of different medicines. The premise of replaceable pot is to conveniently and quickly disassemble and assemble the pot, as well as the operation requirements, noise and stability of the granulation equipment. At present, the corresponding operation requirements have been met through the customized coupling 11. Therefore, in order to further improve the function and practicality of the high-speed wet granulator, the detachable function of the pot body 2 is added.

[0049] Firstly, a main slurry shaft 10 is added to rotate vertically at the bottom of the pot body 2. On the one hand, it cooperates with the stirring shaft 3 on the side wall to improve the granulation effect. On the other hand, it can be aligned with the mounting groove on the coupling 11 connected to the motor to achieve a detachable connection. For example, the mounting groove is square, which makes alignment easier. Based on this, the high-speed wet granulator can be adapted to 5 pot bodies 2 of different volumes (0.5L, 1L, 2L, 4L, 8L). The larger speed regulation range and pot bodies 2 of different volumes can meet the process requirements of most research and development processes for wet granulation. This equipment is suitable for the research and development of Chinese and Western medicines.

[0050] Secondly, the positioning of the pot body 2 on the work surface 102 can be completed in various forms to achieve quick disassembly; for example, a cylinder seat flange is set at the bottom of the pot body 2, and a fixed flange is set on the work surface 102. After the two flanges are aligned, they are fastened with a clamp to achieve quick disassembly and assembly, and the clamp can be loosened for quick disassembly; for another example, a pin hole is set on the side or bottom of the pot body 2, and a pin is set at a corresponding position on the work surface 102. During installation, the pin hole of the pot body 2 is aligned with the pin on the work surface 102 and inserted, and then the pin is fixed by a locking device. During disassembly, the locking device is loosened and the pin is pulled out to quickly remove the pot body 2.

[0051] like Figure 10~Figure 16 As shown, in some examples, the bottom of the pot body 2 also has a locking hole 201 divided into an insertion section 2011 and a locking section 2012, and also includes a locking piece 12 arranged on the work surface 102, which is used to lock the pot body 2 on the work surface 102 through the locking section 2012 after the locking piece 12 extends into the insertion section 2011.

[0052] An improved disassembly positioning form (rotational locking form) is provided to facilitate operation on pot bodies 2 of different volumes. Specifically, a ring plate is integrally formed at the bottom of the pot body 2, and the main slurry shaft 10 is located at its center. A vertical locking hole 201 is provided on the inner wall of the ring plate, which is divided into an insertion section 2011 and a locking section 2012 that is locked after rotation. A locking part 12, such as a bolt or a locking pin 1202, is pre-installed on the work surface 102.

[0053] During installation, align the locking hole 201 at the bottom of the pot body 2 with the position of the locking piece 12, then lower the pot body 2 so that the locking piece 12 extends into the insertion section 2011, and when the pot body 2 is rotated, the cap of the locking piece 12 is stuck in the locking end to complete the locking positioning; otherwise, disassembly is completed.

[0054] 10. Figure 10~Figure 16 As shown, in some examples, improvements are made based on the above locking form, for example, the locking holes 201 are increased to two and symmetrically arranged on both sides of the main slurry shaft 10, so as to fully and stably lock the pot body 2.

[0055] The locking member 12 is composed of a locking cap 1201 and a locking pin 1202. The top and bottom of the locking cap 1201 are respectively provided with an avoidance slope 1203 and a guide slope 1204, both of which are annular. The elastic member 13 in the form of a tension spring is used to enable the locking member 12 that slides vertically to provide a vertical force to the pot body 2 to ensure that it does not shake up and down; wherein, the avoidance slope 1203 can guide the pot body 2 to smoothly approach the locking member 12 when the pot body 2 is lowered, and extend into the insertion section 2011 to avoid collision; the guide slope 1204 can shorten the lowering process of the pot body 2, and the rotating pot body 2 can quickly pull out a part of the locking member 12 upwards under the guidance of the guide slope 1204. Since the elastic member 13 always provides a downward force to the locking member 12, the locking cap 1201 can be locked in the locking section 2012 at this time, and the pot body 2 can be prevented from shaking up and down after being locked.

[0056] Since the whole is a rotational locking form, the locking section 2012 is arc-shaped, and its diameter is smaller than the diameter of the circular insertion section 2011 to ensure the normal use of the locking function.

[0057] The above structure can complete the installation and disassembly process by simply moving up and down and rotating the pot body 2. The operation is convenient, which greatly improves the efficiency of replacing the pot body 2 and meets the rapid switching of different production needs.

[0058] The main pulp shaft 10 is located between two symmetrical locking holes 201, the diameter of the locking section 2012 is smaller than the diameter of the insertion section 2011, and the locking member 12 includes a locking cap 1201 and a locking pin 1202 connected in sequence from top to bottom, the top of the locking cap 1201 has an avoidance slope 1203, the bottom of the locking cap 1201 has a guide slope 1204, the locking pin 1202 is vertically slidably set on the work surface 102, and also includes an elastic member 13 mounted on the locking pin 1202, and its two ends are respectively connected to the locking pin 1202 and the frame 1, which is used to provide a force for the locking pin 1202 to approach the work surface 102.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
